The shadows are not real-time. They're like HL2 shadows, baked in, as others have said. NPCs have shadows, but they're not unified and draw similar to HL2 shadows, just under their feet. The sun is not like a giant light bulb that creates shadows and lengthens and shortens them in the game. It's all static. DOOM 3 is more impressive on the technical side.

I'm so disappointed in RAGE and id tech 5. id tech 4 is much more impressive. Anyone who decides to license id tech 5 is an idiot.
